[0006] Furthermore, the first through groove is linear, the second through groove is arc-shaped, and the first through groove and the second through groove form an I-shape.

[0007] Furthermore, at least one mounting through hole is provided on any one of the bases, and at least two mounting screw holes are provided on any one of the clamping bodies.

[0008] Furthermore, the number of the mounting through holes on any one of the bases is two, a countersunk groove is provided on the bottom surface of any one of the mounting through holes, and the number of the mounting screw holes on any one of the clamping bodies is four.

[0009] Working process:

[0010] Two parallel clamping bodies clamp the workpiece through the clamping cavity, and the clamping force point can be adjusted at multiple angles through the movable groove of the I-shaped structure, which is convenient for clamping arc-shaped, small or special-shaped workpieces.

[0011] Compared with the prior art, the invention has the beneficial effect of clamping arc-shaped, small or special-shaped workpieces well. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example 1

[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The present invention provides a clamp capable of clamping workpieces of various shapes, comprising two symmetrical clamping bodies 1, wherein the two clamping bodies 1 are arranged in the same plane, and an arc-shaped recessed clamping cavity 2 is respectively arranged on the facing side walls of the two clamping bodies 1, and a base mounting step 3 is respectively arranged at both ends of the bottom of any clamping body 1, and a base 4 is respectively arranged in any base mounting step 3, and a first movable groove 5 is arranged in any base mounting step 3, and any first movable groove 5 includes a first through groove 501 and two second through grooves 502, and the two second through grooves 502 are respectively arranged at both ends of the first through groove 501, and any first movable groove 5 vertically penetrates the clamping body 1, and a second movable groove 401 is respectively arranged in any base 4, and the geometric shape and size of the second movable groove 401 are the same as those of the first movable groove 5, and the positions overlap up and down.

[0020] Furthermore, the first through groove 501 is in a straight line shape, and the second through groove 502 is in an arc shape, and the first through groove 501 and the second through groove 502 form an I-shape.

[0021] Furthermore, at least one mounting through hole 402 is provided on any one of the bases 4 , and at least two mounting screw holes 6 are provided on any one of the clamping bodies 1 .

[0022] Further, the number of the mounting through holes 402 on any one of the bases 4 is two, the bottom surface of any one of the mounting through holes 402 is provided with a countersunk groove 403, and the number of the mounting screw holes 6 on any one of the clamping bodies 1 is four.

[0023] The working principle of this embodiment:

[0024] Two symmetrically arranged clamping bodies 1 clamp the workpiece through the clamping cavity 2. The position of the clamping body 1 is adjusted through the movable groove of the I-shaped structure so that the clamping cavity 2 contacts the workpiece in a symmetrical position, which is used to clamp arc-shaped or small workpieces; the positions of the two clamping bodies 1 are adjusted separately so that the clamping cavity 2 contacts the workpiece in an asymmetrical position, which is used to clamp special-shaped workpieces.

[0025] Specifically, the base 4 is made of metal, and the clamping body 1 is made of resin. When the clamping body 1 is damaged, it only needs to be replaced without replacing the base 4 .

[0026] Specifically, first use a screw to pass through the mounting through hole 402 from the bottom surface of the base 4 and then threadedly connect it with the mounting screw hole 6 at the bottom of the clamping body 1 to fix the base 4 to the clamping body 1, and then use a long screw to pass through the first movable groove 5 and the second movable groove 401 to install the clamping body 1 and the base 4 on the cutting machine, and the clamping angle can be adjusted by loosening the long screw.
